The Mellanox SB7890 is a groundbreaking 36-port non-blocking EDR 100Gb/s InfiniBand smart switch system, designed for high-performance computing and enterprise data centers. It delivers an industry-leading 7.2Tb/s aggregate throughput with ultra-low latency of 90ns, making it the ideal solution for data-intensive applications. This network switch incorporates innovative in-network computing technology to accelerate collective operations and optimize fabric performance.
The SB7890 leverages Mellanox's Switch-IB® 2 technology, utilizing 64/66 encoding and 25Gb/s per lane signaling. It supports advanced features like adaptive routing, congestion control, and VL mapping, enabling modern topologies such as SlimFly and Dragonfly+. The integrated SHARP technology allows the network switch to handle collective operations in hardware, significantly reducing CPU overhead and network traffic.
The SB7890 operates as a smart switch by processing data in transit. During collective operations (e.g., MPI reductions), the switch hardware aggregates data packets as they pass through, eliminating the need for multiple transmissions between endpoints. This in-network processing reduces latency and frees up server resources. The adaptive routing engine dynamically selects paths to avoid congestion, ensuring efficient bandwidth utilization across the fabric.
